of_get_mac_address() and of_get_phy_mode() are only provided if OF_NET is configured. While most callers check for the define, not all do, and those who do require #ifdef around the code. For those who don't, the missing check can result in errors such as arch/powerpc/sysdev/tsi108_dev.c:107:3: error: implicit declaration of function 'of_get_mac_address' [-Werror=implicit-function-declaration] arch/powerpc/sysdev/mv64x60_dev.c:253:2: error: implicit declaration of function 'of_get_mac_address' [-Werror=implicit-function-declaration] Provide empty functions if OF_NET is not configured. This is safe because all callers do check the return values.
